Abstract

Plant viruses cause severe damage and significant economic losses to agriculture. Control of virus usually consist ofthe elimination of virus vectors (insects, nematodes, fungi, etc), improvement of the sanitary status of the propagationmaterial, the use of resistance sources in breeding programs. The application of the pathogen-derived resistance strategyhas opened new avenues to protect plants against viruses. Two molecular mechanisms seem to underlie the engineeredprotection, the virus transgene-derived protein and the transgene-RNA interference. A few examples that support theefficiencies of these two molecular mechanisms are reviewed here and discussed in light of the potential use of virusresistanttransgenic plants in agriculture.
